I can't get my pH to rise above 7.8. Is this going to be a problem when I start getting fish? I know a stable pH is better than anything but will 7.8 be too low?

What are the rest of your readings & what salt mix are you using?

As I recall, your system was set up around the 3rd week in Sept., so it was recently cycled, correct? First thing I would do is verify the water tests with another test kit or have your LFS run some tests for verification, just in case you have old reagents. If the test is verified, and providing you don't have any fish or inverts, I would just make a 50 percent water change and your pH should come up.

If it doesn't help, keep doing daily water changes until you see it come up to 8.1-8.3. Your nitrates are already becoming high for sensitive inverts, but not a problem for a fish-only system; at any rate, the water changes will reduce nitrates as well. I want to reiterate; if you have livestock you want to avoid fast changes in water chemistry including rapid shifts in pH.
